Ive done 28 with me and a buddy going upriver on the yellowstone with a tail wind. Its plent fast loaded with my fat ass and a fat friend and dogs and gear. Freighted (3 guys and all the required waterfowl gear) its in the 15-18 mph upriver range 20+ downriver. Depending on the river thats faster than you should be running. LOL Problem with a Jet is, its balls to the wall or you have no steering. You learn to make quick decisions LOL

....its like taking x-lax when you have a bad cough. It wont clear up your lungs, but it sure stops you from coughing
